things you never knew existed. it's a rare film for really allowing us to see the pressures and the constraints and the demands on masculinity on men for an ideal of masculinity. i think in lang's kind of worldview, what he sees is that that little guy is going to lose, you know, that the cynics of the world are going to be able to prey on people who are believers. "scarlet street" could be considered film noir for a number of reasons. first of all, you have a kind of illusion of bourgeois or petty bourgeois order which the bank clerk represents, and that is disrupted. he's cast out from his normal existence into a dangerous, glamorous street world. that sequence when chris cross first sees kitty is close to being the essence of noir. it stopped raining. yeah, a half-hour ago. oh, which way is it to the east side subway?
